once fuel lines are off, how do you remove the injectors? just pull them out ?
and are the injectors tuned to ecu?
injector removal
Yeah,
Once the lines are off and you remove that little metal bracket underneath the injector it simply pulls out. It will be a little snug because of the o-ring.
I don't think the injectors are tuned with the ECU because the flow rate is controlled from the ECU and not the injector. Although because of tolerances and such there still could be a little better flow rate from one injector to the next. I have actually heard that after a period of time, depending on fuel and additives the the inside of the injector almost gets a polished finish.

The Injector Offset and Injector Flow Rate are specific settings in the ECU tuned for the specific injectors in your motor. If you change injectors, you would need to reset these settings to match your new injectors. This could be tricky because you have no real starting point, unless you have the injectors flow tested.
